AFX Holdings manufactures agitators and peristaltic pumps. The AFX Peristaltic pump range is designed as a pumping solution for high viscosity, high solids (abrasive), high density slurries and liquids for applications in mining, chemical, food and beverage, pulp and paper, petrochemical, pharmaceutical, agricultural, water treatment and other industries. The AFX PUMP SERIES offers flow rates from 40 l/hr to 150,000 l/hr, with the 150mm pump delivering maximum flow rate of 147m³/hr and pressures up to 10 Bar, suitable for thickener underflow applications.

AFX manufactures agitator shafts to stringent straightness tolerance of 1mm/metre of shaft length, produces various types of impellers for different applications including high viscosity blending, and manufactures mounting bases and bearing pedestals. All manufacturing drawings are produced in 3D, with Finite Element Analysis (FEA) conducted for large or unusual components. Computational Fluid Dynamics (CFD) is used to visualise gas or liquid flow and its effects.

Peristaltic hose design use high-quality compounded rubbers reinforced with four individual layers of braided nylon. Each hose is precision machined to exacting tolerances. All hoses exceed ISO 1307 and DIN7715 requirements. Available hose liner materials include Natural Rubber (NR), EPDM, Nitrile (NBR), and CSM (Hypalon). AFX supplies hoses produced to original tolerances for many major peristaltic pump manufacturers’ pumps. Pulsation dampeners can eliminate up to 90% of pressure spikes. Hose Failure Detectors sense rises in liquid level within pump housing when hose fails.

AFX manufactures eleven AFX peristaltic pump models: AFX010, AFX015, AFX020, AFX025, AFX032, AFX040, AFX050, AFX065, AFX080, AFX100, AFX150. Pumps are self-priming, fully reversible, highly durable, easy to maintain, can run dry for extended periods without damage. AFX can demonstrate energy savings and maintenance downtime savings of up to 50% compared to traditional peristaltic hose pumps.

AFX designs and manufactures impellers including F3, FS4, P3, P4, folding impellers, R6, and FCE3 Clean Edge Impeller. The F3 hydrofoil impeller is used where high flow velocity is required and is one of the most commonly used throughout industry. The FS4 pitch blade turbine impeller is used for blending, high viscosity blending, applications requiring shear, and re-pulping. The P3 high solidity hydrofoil impeller is used in high viscosity, low Reynolds number fluids for macro flow. The P4 high solidity hydrofoil impeller is designed for large volumes of gas induction in high-pressure autoclaves, BIO oxidation reactors, bacterial leaching, fermentation and hydrogenation, iron removal, and cyanide detox applications. Folding axial flow impellers are adapted for vessels with limited opening diameter. The R6 radial flow impeller is designed for pumper mixer applications. The FCE3 Clean Edge Impeller eliminates ragging in wastewater treatment applications.

AFX designs and manufactures sparge rings, air induction devices, non-clogging nozzles, baffles, baffle coils, pedestals and mounting bases. Non-clogging nozzles are spring loaded, act as one-way valves, have low maintenance with few wearing parts, are manufactured from high grade stainless steel with ceramic tips, and are available in varying sizes for both low and high pressure applications. Baffles and baffle coils are used for heating or cooling in mixing applications. AFX has had success retrofitting equipment in a large Gold Plant in West Africa and a major Platinum plant in South Africa.

AFX offers complete operating solutions for pilot and bench plants, focusing on projects deemed too small for larger manufacturers. AFX has had successful bench and pilot plant installations in bacterial leaching studies, liquid fertiliser processing, and new product launches with personal care industries.

AFX specialises in the design and manufacture of static in-line mixers. These mixers are flanged and bolted into existing process pipelines. Some have as many as seven inlets for various probes and technical apparatus. Inner diameter ranges from 25mm to exceeding 600mm. Elements within the mixer are mirror image structures strategically placed for required mix as stream moves through mixer length.

AFX manufactures side entry agitators for applications where installation of top entry mixers may not be possible due to tank construction and load limitations, or area limitations overhead. Side entry agitators are used in petrochemical and petroleum, animal and plant oils, food and beverage and pulp and paper industries.

AFX supplies pressure oxidation, gas dispersion, iron removal, and cyanide removal solutions. AFX has supplied agitators for autoclaves used in nickel, copper and platinum projects. Dual impeller agitator combinations of P3 and P4 have been installed on numerous plants. AFX has developed an eight-point bull horn sparger to handle high volumes of air in iron removal processes. Solvent extraction (SX) mixer solutions are supplied for pregnant liquor solutions contracted with organic solvents.

AFX provides repair and refurbishment services including on-site hose replacement service for both AFX and 3rd party peristaltic hose pumps. Service is completed to ISO 9001:2015 accreditation and is CE certified. AFX offers preventative and contract maintenance programmes, diagnostic, performance and hydrostatic testing and inspection, site surveys, design, installation and commissioning of mixing and pump systems. AFX provides training options including hands-on training at client sites or AFX facilities, and customised courses. AFX provides mixer audits and pump audits using simulation packages to pinpoint weaknesses in existing designs.
